Document clickhousectl Cloud Postgres support

[sdairs]

Summary

clickhousectl now supports managing ClickHouse Cloud Postgres services (in addition to ClickHouse). This adds a Postgres services section to the ClickHouse CLI Cloud features page (/cloud/features/cli) covering the new clickhousectl cloud postgres commands: list, create, get, update, reset-password, read-replica create, restore, and delete. The page intro is also updated to mention Cloud Postgres.

Command syntax was taken from the clickhousectl README.

Note: the equivalent local + cloud Postgres docs for the /interfaces/cli page live in the ClickHouse/ClickHouse repo (that path is synced in at build time) and are handled in a separate PR there.
